BY filo-MM ZVIIIA Filed July 10, 1950 will? Patented July 28, 1953 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to a nonsegregating conveyer chute and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a flexible chute comprising a pair of belts of flexible material each of which is provided with an outwardly extending tapered wall section adjacent each edge thereof, the wall sections likewise being formed of flexible material. Grommets are formed in the belt at the base of the wall sections wherever required. The device is particularly useful for the pouring of concrete between the walls of forms, one of the devices being placed upon each of the walls of the form in opposite relation to each other. The wall sections of the device may abut one another or, in the case of relatively thin forms, be placed next to one another. In such positions concrete mix may be poured between the sections of the device to thereby impede the rapid flow of mix therethrough and thus prevent segregation of the larger and smaller elements forming such mix.

It is accordingly an object of the invention to provide a simple device of the character set forth having means for the prevention of segregation of the elements of a plastic composition.

Another object of the invention is the provision of a device of the character set forth having all of the parts thereof of a flexible nature.

A still further object of the invention is the provision of a device of the character set forth having novel means for mounting the same upon a concrete form or the like.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

Figure 1 is fragmentary perspective view of an embodiment of the invention shown in position upon a concrete form,

Figure 2 is a perspective view of one element of the invention,

Figure 3 is a horizontal sectional view of the device as utilized with a relatively wide form,

Figure 4 is a view similar to Figure 3 but showing the device as utilized with a relatively narrow form, and

Figure 5 is a fragmentary sectional view taken along the line 5-5 of Figure 1.

Referring more particularly to the drawing,

7 there is shown therein a nonsegregating conveyer chute comprising two complementary parts each part of which consists of an elongated flexible belt l0 formed of rubber or similar material and provided along each adjacent edge of one side thereof with a longitudinally and outwardly extending wall section II. The wall sections I I are frustro-conically shaped as viewed in cross sectional area with the base portions thereof attached to the belt l0. The wall sections H are likewise formed of rubber or other flexible material.

Grommets 12 are formed in the belt at the base of each of the wall sections ll whereby to permit attaching the units to adjacent units or to the form.

In operation, it will be seen that two of the parts of the device above described are utilized together to form a chute in accordance with the invention, each being lowered into the space between, for example, walls It and I l of a concrete form in such manner that the opposed wall sections I I abut each other (in the ease of a relatively wide form as illustrated in Figure 3) or with their opposed wall sections H adjacent each other as shown, for example, in Figure 4 where a relatively narrow form is illustrated. When the device has been so arranged between the walls i3 and M, the upper ends thereof are allowed to overlap the upper ends of the walls I3 and I4 and are attached when necessary to the walls of the concrete form by a nail through a grommet. Concrete mix may then be poured into the chute thus formed by the two parts of the device and, due to the confinement of such mix between the belts It and the wall sections II, will prevent the rapid dropping of such mix and hence prevent the heavier particles thereof from dropping more rapidly than the remainder of such mix, thus preventing undue segregation of the mix to thereby provide a more satisfactory and more evenly distributed texture in the completed structure.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

In combination with a concrete form having a pair of spaced parallel vertical walls, the provision of a pair of flexible belts each supported by one of said vertical walls and extending downwardly upon the inner face thereof in opposed relation to the other, and a pair of inwardly extending flexible wall sections each affixed adjacent an edge of each belt, said sections of one belt being in contact with the sections of the other belt to form with their attached belts an enclosed chute.
